The regular monitoring of toxic metals in sewage, effluents and vegetables is quite essential toavoid their excessive absorption/consumption in the food chain.The quantification of heavymetals in wastewater (sewage/industrial water), soil and vegetables grown in suburb area (BabuSabu Toll Plaza)Lahore, Pakistan during 2015-16 have been investigated. These heavy metalsinclude; Pb, Hg,Zn, Cu and Cd. For brief survey, 20, 20 and 90 samples of sewage water, soiland vegetable, respectively were collected for study. In wastewater, the concentration of heavymetals is observed as Zn > Cu > Cd > Pb, however, Hg was under detection limits.The measuredvalues when compared with WHO standards, these were slightly higher than the safe limits. In soilsamples, concentration was observed as Zn > Cu > Pb > Hg > Cd and is in the safe limits. Thevegetables were found contaminated with heavy metals exhibiting concentration little higher thanpermissible limits of WHO/FAO.
